MF-135 Z-145 misffire

When not used for few weeks when I start the engine
clearly hear one cylinder not firing at exhaust after one minute it runs normaly on the 4 cylinders.

Looks like one valve sticking..I tried some 2 stroke
engine oil in the gas...no change.

Any ideas ?

Thanks in advance

You can try MMO in the gas (1 pt per tank full) or remove the valve cover and spray brake cleaner on the offending valve.
